hairy dark matter

Read an interesting article found on Astronomy magazine's web site. Recent astronomer simulations suggest that dark matter, as it passes through a planet or star, might form into fine, very dense filaments or hairs. Gary Pr├ęzeau of JPL describes these hairs having roots and tips with the roots starting relatively close to the surface of a planet. Looks like a spiky urchin.

And here I thought dark matter was lumpy.
